Analysis and Application of Technical Transformation Scheme for Efficient Recovery of Light Hydrocarbons in an Offshore Oilfield WANG Rui, DAI Qijia, XU Xuezhi, FANG Gang 2023, 50 (1):  34-36.  Abstract ( 434 )   Save Light hydrocarbon is an associated by-product produced in the process of oilfield exploitation. Light hydrocarbon recovery refers to the process of recovering the heavy components in natural gas in liquid form. The natural gas produced by an oilfield is used for turbine power generation,and the remaining natural gas is burned and vented through flare. In order to make rational use of oilfield light hydrocarbon resources,eliminate the impact of light hydrocarbon on equipment process in time,and reduce the environmental pollution caused by insufficient combustion of light hydrocarbon,an efficient and low-cost light hydrocarbon recovery and transformation scheme is designed. By optimizing and upgrading the treatment process of condensate separator of low-pressure compressor,the recovery and utilization of light hydrocarbon is realized. The successful implementation of the scheme has successfully solved the problems of black smoke of oilfield flare and resource waste,which has high reference and popularization significance.

Service Characteristic Analysis of Shock Absorber Based on Road Load Spectrum ZHANG Wenchao, PANG Fangchao, NIU Zhihui 2023, 50 (1):  42-44.  Abstract ( 427 )   Save In order to more accurately reveal the performance degradation of double tube shock absorber during service through the test,based on fully understanding the working state,heat generation and heat transfer of the shock absorber,the damping performance degradation curve of the double tube shock absorber during service is accurately obtained by taking the road load spectrum collected in a test field as the driving signal input,and taking three different working temperatures as variables. The results show that under the condition of specific load spectrum,the damping value of the shock absorber will decrease with the increase of working temperature,and the higher the working temperature during service,the faster the performance degradation of the shock absorber. During the service period,the shock absorber is greatly affected by the operating temperature of the oil. The change of temperature will cause the change of the oil properties,thus affecting the damping characteristics of the shock absorber,and ultimately affecting the degradation rate of the service characteristics of the shock absorber.

Optimization Design and Reconstruction Effect of Remote Control of Water Injection Wells in Offshore Oilfields WANG Kun, WANG Song, LIU Xiaoliang, FENG Haitao, YU Haocheng, WANG Ligang 2023, 50 (1):  56-58.  Abstract ( 398 )   Save In the process of offshore oilfield development and production,it is necessary to maintain the formation energy in the process of oilfield development and production through formation water injection,and its effect determines the quality of offshore oilfield development and production. Water injection is carried out by continuously pressurizing water injection pump to meet the requirements of design water injection pressure. With the increase of oilfield production years,the water content and water injection volume of the oilfield also increase year by year. Therefore,it is necessary to continuously improve and optimize the water injection system to ensure that the equipment operates in the best working condition area,so as to meet the requirements for the design water injection pressure of offshore oilfields. The remote control of water injection wells in offshore oilfields is optimized through the configuration of central control system to realize the remote control of water injection wells under abnormal working conditions,thus avoiding the process shutdown caused by water injection process in offshore oilfields,improving the production efficiency of offshore oilfields,and ensuring the stable and safe operation of offshore production platforms.

Reliability Improvement Scheme and Implementation Effect of FPSO Seawater Lift Pump YU Haocheng, ZHANG Hongwu, WANG Song, FENG Haitao, WANG Kun 2023, 50 (1):  68-71.  Abstract ( 450 )   Save The seawater lift pump equipped by the Offshore Oil FPSO is a large-flow single-stage centrifugal pump,and its main function is to provide cooling seawater and fire-fighting water for offshore oil facilities. Due to the large amount of impurities in seawater and the strong electrochemical corrosion of seawater to metals,the mechanical seal of the seawater lift pump frequently leaks,and the seawater enters the bearing chamber along the direction of the pump shaft,causing the bearing to be damaged. This paper takes the transformation of the seawater lift pump as the background,and conducts research by changing the mechanical seal form,redesigning and installing the bearing water retaining plate,etc.,and finally optimizes the maintenance procedure,increases the bearing service life,and improves the reliability of the whole pump.
